Crush and boil blueberries in 1-1/2 gallons of water for 10 minutes. Strain out berries. Add grains and steep. Add extract and hops and bring to boil. Strain into fermenter with enough cold water to make 5 gallons. Pitch yeast. Give this lots of time in the secondary fermenter or add champagne yeast after initial fermentation. This tastes like a normal stout, but after 4 or 5 sips, a warm glow begins to suffuse your throat and tummy; great for winter nights. Don't worry about pectin haze, you definitely won't see it!
